[1]} observed three H2CO transitions \(3_{03}\) –\(2_{02}\) , \(3_{22}\) –\(2_{21}\) , and \(5_{05}\) –\(4_{04}\)  towards W28 F to determine both kinetic gas temperature and density. Using the methods prescribed by [2]}, they used the intensity ratio \(3_{03}\) -\(2_{02}\) /\(3_{22}\) –\(2_{21}\)  of 3.25 to estimate the kinetic temperature \(T_{\rm kin}\)  = 80\(\pm \) 10 K. From our data we get a value of \(3.9(4)\)  for the same ratio. Similarly, [1]} also used the \(3_{03}\) –\(2_{02}\) /\(5_{05}\) –\(4_{04}\)  ratio to determine the density, interpolating between the LVG models of [2]} using the kinetic temperature of 80 K to obtain \(n_{{H2}}\)  = \({2e6}\,{}\) . Our results obtained form the non-LTE RADEX model are consistent with their results.
